  1. Gear . . . DOWN / 3 GREEN
  2. Repeat after me: "Three green, four in the air." This is critical. You don't want to move to the next step in the checklist until you've ensured all four WOWs are in the air mode.

    Why? See WOW Fail for an explanation of why and GV N777TY for a description of what can happen if you skip this step. Note also that Gulfstream now says the three green lights in the gear handle take priority over what you see in the synoptic. (The three green lights in the gear handle panel are wired directly, the synoptic uses the same switches but they are reported through the MAUs.)

  3. GND SPLR . . . ARMED
  4. The switch light should be illuminated. If you miss this step, your first indication will be the aircraft will not plant itself once the main gear have touched down and the second step will be a sense that braking isn't as good as it usually is.

  5. Brakes / Hydraulics / Brake Accumulator . . . CHECKED / 3000 PSI
  6. Make sure you have the brakes page displayed someplace where both pilots can see it. If you have an Anti-skid Failure or a malfunction requiring Braking Using Emergency Brake, you will need this page in view. You should also take a quick look at the hydraulics synoptics to ensure you have 3000 psi and adequate quantity in both systems.

  7. NO SMOKE . . . ON
  8. FLAPS . . . SET FOR LANDING
  9. Airspeed . . . VREF + 5 KNOTS
  10. I don't wait for the actual speed, I just note the correct speed is bugged. The correct speed should be VREF plus half the steady state wind plus the full gust, but the additive must be at least 5 knots and no more than 20 knots.

  11. WARN INHIBIT . . . INHIBIT
  12. Some operators intentionally skip this step, reasoning they want to know if they are having any issues. I select INHIBIT because the book tells me too. But I am on the fence about the technique.

  13. Flight Controls Synoptic Page . . . SELECT

To answer another frequent question: yes I live in fear of law suits and have reached out for permissions where possible. Gulfstream has been very good about all of this provided I add the note shown below. Let me be clear about this: I think the world of Gulfstream Aerospace. There is no prettier wing in existence than what you see on a GV or G550 and the best cockpit I've ever touched is in my trusty G450.
